Why the Application Can’t Request an Activation Code from Our Servers: Troubleshooting Port 443 Issues.
Once our application has confirmed the email address entered matches a completed sign-up, it will notify our servers that an activation code is required. The application will attempt to send data to the combine via Port 443. Port 443 is the default port for secure web traffic using the HTTPS protocol, which is why our application uses this port to transfer any sensitive data.
However, an application may not be able to send outbound data via port 443 due to various reasons, some of which are:
- Firewall restrictions: Most organizations implement firewalls to restrict outgoing traffic on port 443 to prevent data leakage or unauthorized access to the network. If an application is not authorized or does not have permission to use this port, it may not be able to send outbound data.
- Network errors: Network errors such as DNS resolution issues, incorrect IP configurations, or other connectivity problems can also prevent an application from sending outbound data via port 443.
- Anti-virus or security software: Anti-virus or security software installed on the device may prevent an application from sending outbound data via port 443 if it suspects malicious activity. In such cases, the application may need to be added to the software’s exception list or the software may need to be temporarily disabled to allow the application to send outbound data.
An application may not be able to send outbound data via port 443 due to various reasons such as firewall restrictions, network errors, or anti-virus or security software. Proper troubleshooting of these issues can help resolve the problem and allow the application to send outbound data via this port.
Troubleshooting Email Delivery Issues for Activation Codes.
If you are not receiving an activation code from our servers, despite not having any issues sending outbound data via port 443 and our support team confirming that the email has been sent, there are a few reasons why this may be happening.
- Check Junk/Spam folder: Sometimes, email providers automatically mark incoming emails as junk or spam, especially if the email contains links or attachments. As a result, the email may not appear in the user’s inbox but may be found in their junk or spam folder. If this is the case, the user can mark the email as “not spam” or “not junk” to ensure future emails from our servers are delivered to their inbox.
- Email Whitelist: Some email providers have a whitelist feature that allows users to add specific email addresses or domains to their approved sender’s list. If our domain, block64.com is not on the user’s whitelist, the email may be blocked or sent to the junk folder. In this case, the user can add our servers’ email addresses to their whitelist to ensure future emails are delivered to their inbox.
- Email Delivery Delay: Email delivery can sometimes be delayed due to issues with the email provider’s servers or network. If the user has checked their inbox and spam folder and still hasn’t received the email after a reasonable amount of time, they may need to wait a little longer for the email to arrive.
If your application is not receiving an activation code from our servers, despite not having any issues sending outbound data via port 443 and our support team confirming that the email has been sent, the email may be in the user’s junk or spam folder, our servers’ email address may not be whitelisted, or the email delivery may be delayed. The user can follow the above troubleshooting steps to resolve the issue and receive the activation code.
